Economic Impacts of Legume Varieties and Rotations The Case of Fababeans in the Wheat Based Production Systems of Morocco
While the impacts of cereallegume rotations on soil health are well documented the literature on their economic benefits is scanty By applying the propensity score matching and endogenous switching regression methods to a nationally representative sample of 1230 farm households from the wheatbased production systems in Morocco this paper provided empirical evidence that 1 the adoption of improved fababean varieties led to 2062 kgha 16 increase in yields US100ha 11 higher net returns and 16 kgcapitayear 28 increase in fababean consumption 2 The adoption of fababeans wheat rotations led to 26 higher yields and 38 higher net returns from the subsequent wheat crop and 3 the adoption of both improved fababean varieties and fababeanswheat rotations led to 33 higher total farm income At the current average national adoption level of 23 improved varieties led to about 157 thousand tons 14 higher total national faba beans production per year Therefore along the biophysical and environmental benefits documented elsewhere these results suggest that the introduction of improved varieties of legumes as rotation crops in wheatbased systems can also be justified on economic and food security grounds Enhancing wider adoption of improved varieties and legumecereal rotations through creating better access to extension and certified seed delivery services and other means is important
